Item 4. Ownership.

        Reference is hereby made to items 5-9 and 11 of each of the cover
pages to this schedule 13g, which items are incorporated by reference
herein.

        JMP is filing this Schedule 13G because it acts as the investment
adviser of one or more investment partnerships, pooled investment vehicles
and/or one or more client accounts that beneficially hold common stock that
equal the aggregate amount set forth on page 2 of this Schedule 13G (the
"Securities").  As an investment advisor, JMP has been granted the authority
to dispose of and vote the Securities and, therefore, may be deemed to
beneficially own the Securities. The investment partnerships, pooled
investment vehicles and/or client accounts have the right to receive (or the
power to direct the receipt of) dividends received in connection with
ownership of the Securities, and the proceeds from the sale of the
Securities.

        Neither the filing of this Schedule nor any of its contents shall be
deemed to constitute an admission that JMP is, for any purpose, the
beneficial owner of any securities to which this Schedule relates, and JMP
disclaims beneficial ownership as to those securities, except to the extent
of its pecuniary interests therein.

        Under the definition of "beneficial ownership" in Rule 13d-3 under
the Securities Exchange Act of 1934, it is also possible that one or more
members, executive officers or employees of JMP might be deemed a
"beneficial owner" of some or all of the securities to which this Schedule
relates in that they might be deemed to share the power to direct the voting
or disposition of such securities.  Neither the filing of this Schedule nor
any of its contents shall be deemed to constitute an admission that any of
such individuals is, for any purpose, the beneficial owner of any of the
securities to which this Schedule relates, and such beneficial ownership is
expressly disclaimed.

Item 5. Ownership of Five Percent or Less of a Class.

        Not applicable.

Item 6. Ownership of More Than Five Percent on Behalf of Another Person.

        JMP is filing this Schedule 13G because, as the investment adviser
of one or more investment partnerships, pooled investment vehicles and/or



CUSIP No.427096508                SCHEDULE 13G                Page 6 of 9


one or more client accounts that beneficially hold the Securities, JMP has
been granted the authority to dispose of and vote such Securities.  The
investment partnerships and/or client accounts have the right to receive (or
the power to direct the receipt of) dividends received in connection with
ownership of the Securities, and the proceeds from the sale of the
Securities.

Item 7. Identification and Classification of the Subsidiary Which Acquired
        the Security Being Reported on by the Parent Holding Company.

        Not applicable.

Item 8. Identification and Classification of Members of the Group.

        Not applicable.
